when crate custom cell create class uitableviewcell , add nib tablecell; it's clear. want understand how manage situation when should use custom cell in classes use tableview. for example have view controller called "firstviewcontroller" , inside view controller have tableview, import class of tableview cell , create iboutlet reference #import "mycell.h" iboutlet mycell *mycell; in file's owner of mycell class in identity inspector set class of firstviewcontroller, in way can link iboutlet of custom cell easily. in way can use mycell firstviewcontroller, there way share mycell other classes secondviewcontroller? thanks you can create subclass of uitableviewcell, customcell . create xib file,add uitableviewcell root of xib. change identity of uitableviewcell customcell . connect outlets elements of customcell. don't give ownership viewcontroller. instantiate following code in tableview:cellforrowatindexpath: in viewcontroller ...

i've been reading this article , , playing around memberspace idiom while when noticed surprised me within snippet (which compiles without problems: http://ideone.com/hriv5b ): class hugeclass { public: struct memberspace { int f() const { return parent.f; } private: friend hugeclass; explicit memberspace(hugeclass & parent) : parent(parent) {} hugeclass & parent; } memberspace; hugeclass() : memberspace(*this), f(42) {} private: int f; }; i have expected compiler error access of hugeclass::f not allowed because f private in context. hugeclass friend of memberspace , hugeclass may call private constructor of memberspace , why work other way around without explicitly declaring memberspace friend of hugeclass ? by language rules in c++11. nested class member , such has same access rights other member. example: ...

there interface dispatcherlistener in struts2. docs says "a interface tag want execute code on init , destroy of dispatcher ." but how use interface. if create class implements interface, how should configure struts2? when dispatcher instantiated, send listener notification when it's initialized or destroyed. reference , code samples here . the simple usage instantiate bean container via bean tag , add in init method , remove when destroyed did classpathconfigurationprovider . the code raw show idea struts.xml : <bean type="com.opensymphony.xwork2.config.packageprovider" name="mybean" class="jspbean.struts.mybean" /> mybean.java : public class mybean implements configurationprovider, dispatcherlistener { public mybean() { system.out.println("!!! mybean !!!"); } @override public void dispatcherinitialized(dispatcher du) { system.out.println("!!! dispatcherinitialize...
